The tube 8'ex'tends through-the tube 2 and cumferential the tube arid-to gi've a'cori'e'spondi ng mo tion to th tube 8 to which the collar is fixed. Within the groove upon the; collar 10pm- ..movedsas will be hereinafter described to force 'theicollar 10 'and tube 8 against the spring 11, thereby-pushing'the jaws 5 outwardlyin the-jaw guide when the centrifugal forcexactingupon the" jaws willforce them outwardly and so loosenup thechuck, Nor- ,mally', however, the' spring .11 will hold the jaws'i'n'gripping position. .JThe-worm 4 mounted upon the tube? en 'lt'further has a blank segment ha at.

"pendent-1y of the-gear? The ca with'the end-of alever' 18 :p'ivote ifore referredto. I The feedingmeans '3 comprises a feed rod 5 {21 suit ably sup orted upon the rack as by lne'ans of a stan' ard '22 inflwhich the rod may;

be adjusted by means of a set screw 23. The right hand end of this rod engages with the the rod moves to the right as tie rack is also Carries a projection 24 adapted to 'en gagewith the cam 25 mounted upon the le"- normally" held in the position. shown by *meansiof a spring .27.. As the rack moves to -the right, the cam 25 rolls upon the projec- 'arm 1'3 which-operates to throw the end of that lever which engages with the collar10 to the right'and therebyerniits the-chuckle "open as before described onits end oppositethe chuck earriesm cirgrooved collar 10 whiehfis fixed to it; A s rinigl 1-fi'nterposed between the'cbllar loan a collar 12 fixedto the tube 2 tends-to force the collaroutwardly from lward' into hanging. position. The rack el yet, 13 which is pivoted at 26, and the camzjs plication'- above--reterred to' and felfeimvb is or details other 'jects the endof a lever 13 which may. be. i

' thereto.

eeds to the right, the cam 2,5.ivill drop ofl the projection 2% when the chuck will close under the influence of the spring 11. On the return motion from right to left of the rack,

b5 the left hand end of the projection 24 will 7 strike the lower end of the cam and permit-- the pro ection to pass'wititxout moving the lever 13. The rackalso carries the lateral pro ect1on 28 which is adapted to engage 10 with the longitudinally movable pedestal'fi of the flanging means, so that as the rack nears the left 11 and end of its travel the flang ing means will move with it against the ten-n s'ion of the spring 30, and conversely the 15 spring 30 will return the Hanging means to its right hand position against. fixed stop 130 as the rack returns to the right underthe This will 'occur influence of the spring 454. when the blank segment of the gear 16 is 20 reached.

The flanging means comprises a longitudinal member 31 slidably n'lounteddn the pedestal 29, to which member are pivoted the lateral arms 32 which may be of nickel steel-or other suitable material are yieldingly held in extended position by a spring 33.

@Engaging with the rack F is a gear 34 An arm 36 having a projection 37 for receiving the completed mount tubes is loosely mount 5 ed .onit-he shaft and is flexibly connected with the shaft by means of a spring 38. A pin 39 flied in the arm 36 extends into a slot '40 in the rear, while a stop -41 against which 35 the arm 36 abuts limits the movement of the h) tance after the arm has reached the end of its travel. As the rack moves to the right the gear 34 will be turned through an angle suitable to bring the projection 37 into position to receive a completed tube fronrthe 45 chuck and then a short distance further,

after the projection 37* has reached the end 30f its travel, to ,permit a tube to be pushed out of the chuck. 'In this case thegear 34 makes almost a complete revolution.

To prevent sudden motion of the rack and the parts connected thereto, a retarding device, such as a dash-pot 411, is connected The retarding action of the dashot may be regulated by means of a cook 42.

0 make the tubes soft and in. condition to be flanged, burners 43, the flames of which are adapted to play upon the ends of tubes projecting from the chuck, may be provided.

Having described the machine, its operai tion may be outlined as follows Tubes of the proper length having been laced-in the hopper A and the parts having been positioned as shown, the rotation of the pulley G will revolve the chuck, and when, the blank space 20 disengages gear 16 from seaose the rack, thes )ring 44 will move the rack irom its mitia posltion toward the right. This movement of the rack .will cause the feeding rod 2-1 to move from its initial position to push ,a glass tube ahead of it through the tubes 2 and 8, and just as the tube is.

about to enter the chuck the cam 25 will ride upon the projection 24:,thereby permitting -the jaws to open. During the movement oi the rack up to this. point the discharge arm has been movmg', and at this stage it will .rest against the stop 41, the projection 37 being in position to receive a completed tube as it is discharged from the chuck. Further movement ofthe rack'to the rlght will cause the tube to enter the chuck, so that one end projects beyond the chuck, and push a flanged tube which may be in the chuck out upon the projection 37, the lost motion connection between the armj36 and the rack permitting this further movement while'thc arm remains fixed in position. During the right hand movement of the rack, the 1' auging means follows the projection 28, under the influence of the spring 30, 'until it strikes the stop 130, so that at a suitable time the ,flangi'ng means is moved out of the way of the discharging means. When the said flangi'ng means is atthe end of its movement it will occupy a position as shown in the dotted lines of. Fig. ,1. Just as the .rack reaches the end of its travel, the cam 25 will drop of? the projection 24 and the chuck will be closed by the spring 11. The right hand limit of, travel'having been reached, which occurs before the blank segmentof the gear 16 has been passed, the gear 16 returns the rack to the left. As before stated, during 'this movement the projection 24; has no effect uponthe chuck; The projection 28 causes the Hanging means to follow the rack to the end of its travel. Near the end of the left hand end of the travel of the flanging means, the member 31 enters the end of the tube to be flanged which is ,ecurcly held by the chuck, and the'arms 32 c me against the end of the tube. sufllciently soft undertheinfluence of the flames from, the burners 43, the small movement of the fianging means to the left after the arms 32 have come. in contact with the tube, will operate to turn up a flange. During the left hand movement of the rock the arm 36 is turned in a clockwise direction, a completed tubesliding from the projection 37 into a proper receptacle. 1 The movement to the lef being completed, thcparts will then occupy the position asshown in full lines in the drawings and will be in readiness for a repetition of the operation. v 'W'tho'ut limiting myself to the precise construction and arrangement of parts shown, I claim:- v
